Mike,
It's a very simple thing to do. In the beginning of your program,
define a variable to represent the plate thickness: For instance; #100=.750
For your "Z" depths, just program the .05" plus the drill tip.
Now, in your program, have your "Z" represented by: Z-#100+(the numeric
value coded that represents .05+drill tip)
It should be possible to modify your code generator to output this form of
modified code. Or, in your text editor, do a search & replace: "Z-" to
"Z-#100+"
It's been a while since I programmed an OM control. I seem to remember that
the variables are defined a little differently, so you will have to look in
your Fanuc Operators manual, but the logic is the same.

depth using a variable???

Is there a way in which to change the Z-depth value in the G83 peck line to
accommodate various material thickness?
I'm using the program below to c/drill & drill a number of plates. The
plates range in thickness from 1/8 to 3/4.
I can use the same program but I have to change the Z-depth for each plate.
This program is being used on a Hurco milling center with an Fanuc OM
control.
